Measured values for Zinc oxide, and where each one comes from
20 measured values for 7 properties, read from 4 public databases. On 3 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
4 records, 1974 to 1975 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- 3587 °F
- NIOSH Pocket Guide
Vapour pressure
3 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 0 mm Hg (approx)
- Hazardous Substances Data Bank (HSDB)
- 0 mmHg (approx)
- NIOSH Pocket Guide
- 0 mmHg (approx)
- OSHA Occupational Chemical Database
Density
4 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 5.6 g/cu cm
- Hazardous Substances Data Bank (HSDB)
Solubility
6 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Insoluble in water
- Hazardous Substances Data Bank (HSDB)
- Slowly decomposed by water
- Hazardous Substances Data Bank (HSDB)
- Soluble in dilute acid
- Hazardous Substances Data Bank (HSDB)
- Soluble in acids and alkalies; insoluble in alcohol
- Hazardous Substances Data Bank (HSDB)
- 0.00042 g/100 cu cm water at 18 °C
- Hazardous Substances Data Bank (HSDB)
- (64 °F): 0.0004%
- NIOSH Pocket Guide
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- pH = 6.95 (American process zinc oxide); 7.37 (French process)
- Hazardous Substances Data Bank (HSDB)
Odour
1 record
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
Decomposition temperature
1 record
The temperature at which the substance breaks down, often into products more hazardous than itself.
- Chlorinated rubber (at 419 degrees F), water [Note: Slowly decomposed by water]
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Zinc oxide, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
